thanx for asking...
I wasnt really sure how close you can safely have the two sprockets...
You can space your sprockets 1/8" apart if you really want to; neither will move so they'll never make contact
NOTE: That is an exaggeration; it's possible but, I don't recommend it...
I just figured the further back, the more contact the chain has with the circumference of the sprocket... = less likely the chain derails?
Incorrect, you have that backwards; the
closer the two sprockets are, the more contact there is with the axle sprocket.
Because one is much bigger than the other, you will never balance the two so, you will always have less contact on the drive sprocket & more on the driven sprocket but, combined, the angle of coverage will both add up to 360°
please feel free to enlighten me if its safe to have them closer together, it will make phase 3 of my project much easier
It's very safe for a number of reasons:
1. With proper alignment, there's less chance of the chain derailing
2. The closer together they are, the
easier it is to
get proper alignment
3. The weight distribution will improve; the weight should be kept in front of or as close to the axle as possible. more weight on the rear of the kart means less weight on the front which can create steering/handling problems...
